But what's the point of adding an ability that almost never gets used? Very situational abilities can be given to creatures of level 6-7, but not level 4 (I mean that, within the balance, level 4 shouldn't have a bunch of abilities in general, and poorly chosen ones can make the creature unappealing). If they were a replacement for ordinary golems, it might still be useful due to the guaranteed presence of archmages or marsh golems, for example, then it would be acceptable. And there are enough fire abilities - vulnerability aura, liquid flame, explosion, explosion on death, etc. Although, as I already wrote, a shield + 50% damage reduction + immunity to slow is more than enough for a level 4 creature.
well, at level 5, you can even give it a Fire Strike, to guarantee the leveling of the Sign skill. although copying the abilities of the Jarls is not a good idea.
Liquid Flame will look very good on non-dragons, right? The vulnerability aura also looks cool on a unit consisting of magma? The explosion on death is not overpowered, that's why it's not in the final version of the game?
but by the way, we can actually think about the "explosion". We can try to remove the shield from the unit and give it an explosion, what do you think?
